This allows preseeding of a fully configured RAIDed system by setting partman-auto/method to "raid" and using partman-auto-raid/recipe to tell it how to construct the RAID array(s). The preseedable parameter partman-auto-raid/recipe should consist of recipes separated by periods ("."). The recipes are of the form: <raidtype> <devcount> <sparecount> <fstype> <mountpoint> <devices> <sparedevices> where <devices> is a list of the devices to make up the RAID and <sparedevices> is a list of the spare devices in the array; devices are separated by hashes ("#"). For example: d-i partman-auto-raid recipe string \ 1 2 0 ext3 / /dev/sda1#/dev/sdb1 . \ 1 2 0 swap - /dev/sda5#/dev/sdb5 . This must be written all on one line; if you write it across multiple lines you must use continuation characters (as in the example). This makes the first RAID device that was created by this udeb be a RAID1 of two disks disc0/part1 and disc1/part1 and be formatted as ext3 and mounted on /. The second is also a RAID1 and used as swap (and the mountpoint ignored). -- Simon Huggins <huggie@earth.li> sponsored by Black Cat Networks http://www.blackcatnetworks.co.uk/ It is also possible to preseed LVM over RAID. The following example will create a RAID 1 setup on two hard drives with: /dev/md0 as /boot (ext3) /dev/md1 as a LVM physical volume /dev/mapper/<hostname>-root as / (ext3) /dev/mapper/<hostname>-swap_1 as swap /dev/mapper/<hostname>-home as /home (ext3) --- 8< --- d-i partman-auto/method string raid d-i partman-auto/disk string /dev/sda /dev/sdb d-i partman-auto-raid/recipe string \ 1 2 0 ext3 /boot \ /dev/sda1#/dev/sdb1 \ . \ 1 2 0 lvm - \ /dev/sda5#/dev/sdb5 \ . # In the expert_recipe, there is a stanza for each RAID partition # and each LVM partition. # The RAID partitions are tagged as "lvmignore", while # the LVM logical volumes as "defaultignore" and "lvmok". # The RAID partition containing the LVM volumes must be made big # enough to hold them all. # Note that in the example shown here the mountpoint for /boot # (which is not encapsulated within LVM) is specified in the # partman-auto-raid recipe, rather than in the corresponding # raid partition definition below. # d-i partman-auto/expert_recipe string \ multiraid :: \ 100 512 256 raid \ $lvmignore{ } \ $primary{ } \ method{ raid } \ . \ 900 5000 4000 raid \ $lvmignore{ } \ method{ raid } \ . \ 700 5000 4000 ext3 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ $defaultignore{ } \ $lvmok{ } \ method{ swap } \ format{ } \ . \ 100 1000 1000000000 ext3 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext3 } \ mountpoint{ /home } \ . --- >8 ---
